Right now i am learning how to use ICEM, what i want is your opinion about this geometry, this is the fluid volume of a twin screw pump, i will have to mesh this geometry and set boundary conditions, the inner faces are the screws so they will have a velocity, the outside faces will be a wall, what i want to know is:
-Will i have trouble creating the boundary conditions?
-Is there another option to mesh and create the boundary conditions besides ICEM?
